AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BILLINGS MT
242 PM MST WED JAN 4 2012

.SHORT TERM...VALID FOR THU AND FRI...

YET ANOTHER WINDY AND MILD DAY ACROSS OUR FORECAST AREA. DIRTY
ANTI CYCLONIC FLOW OVER THE REGION PRODUCED A GOOD DEAL OF CLOUD
COVER WHICH LIMITED MIXING IN A FEW LOW AREAS SUCH AS SHERIDAN.
SO TEMPS DID NOT REACH FORECAST MAX THERE...BUT BILLINGS AND
MILES CITY EACH REACHED NEW RECORDS THANKS TO A MILD AIR MASS AND
DOWNSLOPE WINDS.

SHORT TERM MODELS IN GOOD AGREEMENT ON TURNING MODERATE RIDGING
FLATTER AND STRENGTHENING UPPER WESTERLY FLOW OVER THE NORTHERN
ROCKIES AS SEVERAL RIPPLES TRACK THROUGH SOUTHERN CANADA THE NEXT
DAY OR TWO.

FOR TONIGHT...ANOTHER GOOD SET UP FOR STRONG WINDS AT LIVINGSTON
AND THE FOOTHILLS AROUND NYE. WIND ADVISORY ALREADY IN PLACE
THROUGH NOON THURSDAY LOOKS ABOUT RIGHT AS PRESSURE GRADIENT WILL
WEAKEN SOMEWHAT BY THURSDAY AFTERNOON. WILL ALSO ADD BIG TIMBER
HIGHLIGHT TO THE MIX FOR TONIGHT THROUGH NOON THURSDAY AS THEY
HAVE BEEN FLIRTING WITH CRITERIA LEVEL WINDS AS WELL AND SEE NO
REASON FOR THIS NOT TO CONTINUE. REST OF FORECAST AREA WILL BE
MILD WITH SOME CLOUDS AND MODEST MIXING.

THURSDAY AND THURSDAY NIGHT...LOW AMPLITUDE TROUGH WILL CROSS THE
NORTHERN ROCKIES PUSHING A COLD FRONT SOUTH. MOST OF THE ENERGY
WITH THIS SYSTEM WILL STREAK EAST WITH THE JET STREAM ALOFT...BUT
THERE IS SOME FRONTOGENESIS PROGGED OVER SOUTHERN MONTANA BY LATE
DAY OR EVENING. HOWEVER...THIS IS SHORT LIVED AND THE SYSTEM
APPEARS RATHER MOISTURE STARVED AND WILL HAVE TO BATTLE STRONG
WESTERLY FLOW. HAVE THEREFORE REDUCED POPS IN SOME AREAS AND SNOW
AMOUNTS FOR THE HIGH COUNTRY. ANY PRECIP THAT OCCURS WILL BE
MOSTLY OVER BY FRIDAY AT SUNRISE. FRONTAL PASSAGE WITH THIS SYSTEM
WILL BE LATE IN THE DAY ALLOWING FOR PREFRONTAL WARMING AND
POSSIBLY SOME NEAR RECORD HIGHS AGAIN THURSDAY AFTERNOON.

FRIDAY AND FRIDAY NIGHT...AS THURSDAY NIGHTS WEAKER SYSTEM EXITS
TO THE EAST...WE WILL HAVE A BRIEF LULL IN BOTH PRECIP AND WIND.
EXPECT COOLER TEMPS IN NW FLOW ALOFT. HOWEVER...ANOTHER TROUGH
WILL TRACK THROUGH THE PACIFIC NW AND IDAHO BY FRIDAY EVENING.
THIS SYSTEM IS TAPPING BETTER MOISTURE FROM THE PACIFIC AND
PLACING OUR WESTERN MOUNTAINS UNDER SOME DECENT CONVERGENCE AND
OROGRAPHIC FLOW. HAVE BUMPED UP POPS FRIDAY NIGHT IN THE HIGH
COUNTRY AND STARTED TO TREND SNOW AMOUNTS UP A BIT IN THE 2-4 INCH
RANGE. MAY REQUIRE FURTHER TWEAKS UPWARD SHOULD PATH OF SYSTEM
REMAIN THE SAME AS GOOD Q VECTOR FORCING IS POSSIBLE. THIS WILL
ONCE AGAIN BE MAINLY A MOUNTAIN EVENT WITH ONLY BRIEF LOW LEVEL
CONVERGENCE PROGGED FROM BILLINGS WEST WHERE WE WILL KEEP POPS
LOW. BT

.LONG TERM...VALID FOR SAT...SUN...MON...TUE...WED...

THE EXTENDED PERIOD BEGINS SATURDAY WITH A STRONG SHORTWAVE
DIVING SOUTH OF THE REGION...WHILE A WEAKER SHORTWAVE MOVES
THROUGH THE REGION FROM THE NORTHWEST. ALTHOUGH THERE WILL NOT BE
A LOT OF MID-LOW LEVEL MOISTURE TO WORK WITH...THERE MAY BE
ENOUGH ASCENT ALOFT TO GENERATE MID/HIGH CLOUDS AND SOME MOUNTAIN
SNOW SHOWERS...WHICH MAY KEEP DAYTIME TEMPS FROM WARMING MUCH
ABOVE THE MID 30S/LOW 40S.

UPPER LEVEL RIDGING AMPLIFIES SUNDAY INTO MONDAY AHEAD OF THE NEXT
SYSTEM. THIS MEANS CONTINUED DRY WEATHER AND A RETURN TO MUCH
ABOVE NORMAL TEMPS...ESPECIALLY CONSIDERING 850 MB TEMPS ARE
PROGGED TO REACH 3-5C BY SUNDAY AFTERNOON...AND UPWARDS OF 6C
ACROSS MUCH OF THE REGION MONDAY AFTERNOON. THE SURFACE PRESSURE
GRADIENT AND 850 MB HEIGHT GRADIENT ALSO TIGHTEN UP AND BECOME
ORIENTED MORE WEST-EAST SUNDAY INTO MONDAY ACROSS THE WEST...WHICH
FAVORS THE WINDIEST CONDITIONS FROM THE BEARTOOTH/ABSAROKA
FOOTHILLS TO BIG TIMBER NORTH TO JUDITH GAP AND EAST TO
ROUNDUP...BILLINGS AND THE YELLOWTAIL DAM/FORT SMITH REGION. WILL
NEED TO KEEP AN EYE ON THE WIND FOR POTENTIAL ADVISORIES ALONG THE
BEARTOOTH/ABSAROKA FOOTHILLS. DID INCREASE WINDS ACROSS A GOOD
PORTION OF THE WEST SUNDAY INTO MONDAY NIGHT.

MONDAY NIGHT INTO TUESDAY...A STRONG COLD FRONT MOVES THROUGH THE
REGION AS FLOW ALOFT BECOMES NORTHWESTERLY. LOW/MID LEVEL
FRONTOGENESIS...UPPER LEVEL DIVERGENCE AND INCREASING UPSLOPE
FLOW AT THE SURFACE MAY GENERATE SOME LIGHT SNOW/SNOW SHOWERS LATE
MONDAY NIGHT INTO TUESDAY...SO INCREASED POPS A BIT OVER THE
MOUNTAINS AND KEPT SLIGHT CHANCE POPS OVER THE PLAINS. IT WILL
ALSO BE QUITE WINDY ACROSS THE ENTIRE REGION TUESDAY INTO TUESDAY
NIGHT WITH STRONG COLD AIR ADVECTION AND STRONG SURFACE PRESSURE
RISES BEHIND THE FRONT.

FLOW REMAINS NORTHWESTERLY THROUGH THE REMAINDER OF THE
EXTENDED...WHICH WOULD GENERALLY KEEP THE REGION DRY.
HOWEVER...THE 12Z ECMWF SHOWS A POTENT SHORTWAVE MOVING THROUGH
THE FLOW TUESDAY NIGHT/WEDNESDAY MORNING WITH A PERIOD OF SNOW
ACROSS THE WEST. THIS IS A SLOWER PROGRESSION THAN THE PREVIOUS
00Z SOLUTION...WHICH ALSO DEPICTED THE SHORTWAVE MOVING ACROSS THE
WEST. CANNOT DISCOUNT THIS SHORTWAVE ACTIVITY AS THE ECMWF HAS
BEEN THE MORE CONSISTENT MODEL LATELY...THUS KEPT A SLIGHT CHANCE
OF POPS ACROSS THE WEST TUESDAY NIGHT INTO WEDNESDAY MORNING. STC

&&

.AVIATION...

VFR CONDITIONS BENEATH PASSING HIGH-LEVEL CLOUDS ARE EXPECTED OVER
THE AREA THROUGH MID DAY THURSDAY. WEST TO SOUTHWEST WINDS WILL
BE GUSTY OVER THE FOOTHILLS IN PLACES LIKE KLVM AND K6S0. GUSTS
OVER 40 KT WILL OCCUR IN THOSE AREAS. A FEW PLACES ON THE PLAINS
COULD ALSO HAVE GUSTS OVER 20 KT INTO THIS EVENING...AND KBIL IS
EXPECTED TO EXPERIENCE GUSTS TO NEAR 30 KTS THROUGH TONIGHT. STC
